Proceedings of the SPIE, 1216, 53-62, (1990).
The authors discuss the
possibility of generating, propagating and detecting THz electrical pulses in
semiconductor quantum well structures and present preliminary experimental results. Recent
advances in semiconductor technology have pushed the performance of electronic and
photonic devices well into the GHz regime. The development of devices operating at many
THz, however, will require novel structures and will implement physical processes
different from those presently used. The authors review their theoretical studies of the
mechanisms that can be employed to generate, propagate and detect THz electrical signals
in properly designed semiconductor quantum well (QW) structures and discuss their recent
experimental investigations of these effects
